(CNN) - An Arizona gun store says it has canceled a recent purchase of an AR-15 semiautomatic rifle by Mark Kelly thwarting the retired astronaut's attempt to demonstrate how easy it is to buy high-powered weapons.

Kelly, the husband of former Rep. Gabby Giffords and an outspoken advocate for new gun control measures, had in recent interviews said he was buying the rifle to showcase what he said are unobtrusive background checks.
